FASTENING DEVICE.

Specification of Letters Patent.

atentecl April 2, 1907.

Application filed July 10. 1906. Serial No. 325,554.

To all whom, it nca/y concern:

Be it known that I, WILLIAM BILLINGSLEY, a citizen of the United States, residing at Quincy, in the county of Douglas and State of IVashington, have invented a new and useful Fastening Device, of which the following is a specification.

This invention relates to fastening devices, such as are adapted particularly for use upon doors, windows, and the like.

The object of the invention is to provide an extremely strong, simple, durable, inexpensive, and thoroughly eflicient fastening device by means of which a door can be held securely in fastened position under normal circumstances and can also be opened by merely pushing upon the same.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the following claims witho ut departing from the spirit of the invention or sacrificing any of its advantages.

' screws, or other devices.

In the accompanying drawings, forming part of this specification, Figure 1 is a horizontal section, partly in elevation, through one side of a screen-door equipped with the improved fastening device of this invention. Fig. 2 is a detail elevation, partly in section, of the improved fastening device. Fig. 3 is a similar view of a modified construction. Fig. 4 is a detail perspective view of the saddle-piece. Fig. 5 is a view similar to Fig. 4 of one of the bolts removed from the casing.

Like reference-numerals indicate corresponding parts in the different figures of the drawings.

The iirst form of the invention preferably comprises a supporting member 1, which is ordinarily in the form of a metallic baseplate and is provided with perforations 2, constituting means for securing it inposition upon a door or window by the use of nails, The supporting member 1 is provided with bolt-guiding means adapted toengage two sides of a bolt 3. The preferred bolt-guiding means consists of a pair of parallel channel-plates 4, which extend longitudinally of the supporting member 1 and are either formed integral therewith or suitably secured thereto. The

bolt 3 preferably is formed a-t its forward end with a straight engaging face 5 and a beveled engaging face 6. The rear end of the bolt 3 is rounded, as indicated at 7, and, furthermore, the opposite sides of said bolt 3 preferably are cut away, as indicated at 8, in order to lighten the bolt, as well as to decrease the amount of material necessary in constructing the same. Adjacent its rounded rear end 7 the bolt 3 is provided with a pair of oppositely-extending trunnions 9, which project through suitable longitudinal slots 10, formed in the bolt-guiding means or channel-plates 4. The rear ends of the longitudinal slots 10 preferably are curved upward, as indicated at 11, to form lateral entrance portions 12, which intersect the upper edges of the channel-plates 4 and permit the trunnions to be readily fitted into or removed from said slots, it being understood that when the trunnions 9 are engaged with the slots 10 they can be readily removed therefrom by merely pushing rearward on the bolt 3, whereby said trunnions will be caused to ride up the curved ends 11 of said slots and pass out through the lateral entrance portion 12.

The means for pushing the bolt 3 yieldingly forward consist, preferably, of a coilspring 14, which is mounted between the channel-plates 4 and extends at its rear end into a spring-casing 15, located between the rear ends of said channel-plates 4. The spring 14 is not secured in the casing 15 in any way, for which reason it can be readily removed therefrom. Loosely fitted against the rounded rear end 7 of the bolt 3 is a saddle-piece 16, having a rearwardly-extending stem 17, which is litted loosely into the forward end of the spring 14, as shown.

The means for normally holding the bolt 3 between the channel-plates 4 preferably comprises a spring which is indicated generally by 20. While the spring 20 may be of any suitable form, it preferably consists of a piece of wirelhaving its ends 21 bent into parallelism and extended along the lower portions of the channel-plates 4, said parallel ends 21 being extended rearwardly through suitable perforations in braces 22, which are secured to the supporting member 1 and channel-plates or bolt-guiding means 4. The parallel ends 2 1 are joined by an intermediate yoke 23, which extends up the sides of the IOO IIO

channel-plates 4 and across the upper edge of the bolt 3, said yoke 23 being in direct contact with said bolt, as shown.

It will be obvious that when the improved fastening device is placed upon a doorsuch, for example, as a screen-door-said door can be readily closed in the ordinary way by reason of the fact that the beveled n engaging face 6 will cause the bolt 3 to slide rearwardly, whereby the straight engaging face will hold-the door in closed position until it is desired `to open the same by a simple push or pull, whereupon the bolt 3 will swing away from the supporting member 1 by pivoting upon its trunnions 9, this swinging movement being permitted by the spring 20, which will yield to the desired extent and will then throw the bolt backward into normal position. It will be obvious that this form of the invention is extremely strong, simple, durable, and inexpensive, for the reason that the supporting member 1 and the channel-plates 4 can be readily cast, and the spring can be applied by simply sliding its rear parallel ends through the braces 22. Furthermore, the coil-spring 14, together with the saddle-piece 16, can be quickly assembled, as it will not be necessary to secure these parts together. If either of the springs 14 and 20 should become worn, a new spring can be easily and quickly supplied.

The modified construction illustrated in Fig. 3 is practically the same in all essential respects as the construction shown in Fig. 1, except that the modified construction is particularly adapted for use upon a car-window.

lIn the modification the parallel channelplates 4, which in Fig. 1 are disposed in planes parallel with each other, are placed in planes at right angles to each other, the channel-plate 25 being secured to the supporting member 1 and the channelplate 26 being secured to the outer edge of the channelplate 25. In this form of the invention only the channel-plate 26 is formed with the longitudinal slot 10, the other slot 10 being formed in the supporting member 1, as shown. The bolt 3, trunnions 9, bolt-spring 14, spring-casing 15, and saddle-piece 16 are exactly the same as in Fig. 1. The spring 20 in the modification is formed with the parallel ends 21, which extend through the braces 22, as previously described. The sides 27 and 28 of the yoke of the spring extend upward at opposite portions of the channel-plates 25 and 26. Adjacent the rear end of the slot 10 inthe channel-plate 26 the yoke of the spring 20 is formed with a resilient coil 29. Adjacent the coil 29 the spring 20 is formed with a longitudinal portion 30, which extends along one edge of the slot 10, as shown. One of the parallel ends 21 of the spring 20 is longer than the other and is formed with a resilient coil 31, which rests flat against the supporting member-1 and is located in a plane which is parallel with the plane of the resilient coil 29. It will be apparent that the operation of the modified construction is practically the same as the operation of the construction shown in Fig. 1. bolt 3 rides over the rack or other engaging shoulders upon the window-frame, and the straight engaging face 5 of said bolt engages When the window is raised, the,

one of the teeth or shoulders of said rack, so

as to hold the window in raised position. When it is desired to lower the window, instead of withdrawing the bolt 3 from its engagement with the supporting shoulder or rack it is only necessary to force the window downward, whereupon the bolt 3 will be permitted to move upward against the tension of the spring 20, which as soon as the bolt has passed the projection will move said bolt into normal position.

The modified construction is characterized by the same elements of simplicity, durability, inexpensiveness, strength, and efiiciency as the construction illustrated in Fig. 1.

The reference-numeral 40 in Fig. 5 of the drawings represents a deadening-plate, which is formed, preferably, of rubber or other soft material and is secured in any convenient manner upon the lower face of the bolt, so that when it is forced back into the casing formed by the channel-plates through the action of the spring the deadening-plate will prevent any noise. 4
